Hi,

I am using ubuntu linux.
How to make a time delay of a more than 30min using C++.

...What?

"How to make a time delay of a more than 30min using C++."

It sounds like you want a timer but I'm not exactly sure. :/

you can use sleep().

it take time in milliseconds.. so calculate how much you need to pass..
it will be around.. (1000 * 60 * 30)

I thought sleep only worked in Windows?

Sleep is the Windows version, the parameter is milli-seconds.
sleep is the Unix version, the parameter is seconds.

usleep() is the *nix equivalent, the argument is in micro-seconds (10^-6).

#if defined(__WIN32__) || defined(_WIN32) || defined(WIN32) || defined(__WINDOWS__) || defined(__TOS_WIN__)

  #include <windows.h>

  inline void delay( unsigned long ms )
    {
    Sleep( ms );
    }

#else  /* presume POSIX */

  #include <unistd.h>

  inline void delay( unsigned long ms )
    {
    usleep( ms * 1000 );
    }

#endif

Just to be complete. ;-)

Hi


Thanks friends......

Sorry for late reply

#include <ctime>

inline void mySleep(clock_t sec) // clock_t is a like typedef unsigned int clock_t. Use clock_t instead of integer in this context
{
clock_t start_time = clock();
clock_t end_time = sec * 1000 + start_time
while(clock() != end_time);
}
